Y l kpplicationcfifd llarch 9, 1am s mi-no..,114,o1a j This inventionvrelates to anti-skid devices,

and comprehend s'a novel construction and In the drawings forming part of this ap plication like numerals of reference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of a wheel showing the application of the invention.

Figure 2 is a plan view of one of the sections of the device.

Fi re 3 is a transverse sectional, view through the device and tire to which it is applied. 7

Figure 4 is a fragmentary sectional view showing how the ad acent sections of the device are connected together.

Figure 5 is a perspective view of one of the ln a eferring to the drawings in detail in-. dicates a wheel equipped with a pneumatic tire 11 about the periphery of which the anti-skid device is adapted to be arranged.

This device is preferably made up of a plurality of sections 12, and each section is preferably of the cross sectional configuration illustrated in Figure 3. These sections may be constructed from any suitable ma terial, preferably metal and. vary in size without departing from the inventive idea. Each section is of a width to extend entirely across the tread of the tire 11 and formed with inturned flanges 13 as illustrated, while each section is also provided with a lining of some relatively soft material indicated at 14.

Figure 2, and each of these straps is progether in any suitablemanner without the necessity of jacking-the wheelofl the ground.

For the purpose of connecting these sections' together I preferably make use of staple-like links indicated at 17, there being two of such links connecting the ends of the adjacent sections. As shown in Figure 4 each link has one of its ends swiveled as at 18 and the openings 16 on one section, while the other ends of the staples terminate to form books which are received by the openings in the strip 15 carried by the other section, the last mentioned openings communieating with openings formed in the section itself. By reason of this construction each section is applied to the tire singly, and as each section is added to the device the hooklike extremities of the links are slipped in the openings 16 of the section being applied.

After all of the sections have been connect- 7 ed together about the periphery of the" tire,

vice in place. Each strap of course is provided with abuckle so that the strap can be properly adjusted for the purpose intended. rranged across the outer surface of each section 12 is a plurality of diagonally arranged metal straps 21 as clearly shown in vided with a series of threaded openings 22 into which lugs 23 are fitted. While these lugs mav vary in size and shape, they are preferably of the construction shown in Figure 5, wherein each lug is provided with a threaded extremity 24 adapted to be screwed into one of the openings 22, and limited in its 7 movement in the direction of the section bya flange 25. The lug proper is preferably tapered as shown. By reasonof this construction the lugs are arranged in a zig zag fashion across the entire periphery of the anti-skid device, which renders the latter particularly effective for the purpose in tended.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent,I e-

sire to have it understood, that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What is claimed is: I i

An anti-skid device for wheels comprising a plurality of segmental sections adapted to be arranged in end to end relation about the periphery of the wheel, transverse metal straps extending across the respective sec tions adjacent the meeting ends thereof, each of said straps having a plurality of openings, and 'stapleJike links connecting said sections together, each link having an oflset headed ortion swivelly mounted in the openings oi one of said straps, the oppo- 15 site end of each link terminating in a hook to be received by one of the openings of the strap carried by the adjacent section.

In testimony whereof I aflix my signature.

m. GEORGE X BLONDO.
